Distributed semiconductor die and package architecture

ABSTRACT

The present disclosure is directed to systems and methods of conductively coupling a plurality of relatively physically small core dies to a relatively physically larger base die using an electrical mesh network that is formed in whole or in part in, on, across, or about all or a portion of the base die. Electrical mesh networks beneficially permit the positioning of the cores in close proximity to support circuitry carried by the base die. The minimal separation between the core circuitry and the support circuitry advantageously improves communication bandwidth while reducing power consumption. Each of the cores may include functionally dedicated circuitry such as processor core circuitry, field programmable logic, memory, or graphics processing circuitry. The use of core dies beneficially and advantageously permits the use of a wide variety of cores, each having a common or similar interface to the electrical mesh network.

TECHNICAL FIELD

The present disclosure relates to semiconductor packaging and die architecture.

BACKGROUND

Next-generation Compute Devices, Programmable Logic (FPGA), Graphics units, (also called Compute Devices) and data centers are trending toward systems providing greater computational capabilities, operational flexibility, and improved power efficiency. The combination of demands presented by next-generation data centers and Compute devices present significant challenges for current general-purpose servers. Increasing demand for reduced system complexity, business agility and scalability has increased demand for virtualized data center infrastructure that will place additional demands on next-generation data servers. To meet such varied requirements, next-generation servers may be designed to address a specific workload matrix. However, such task- or service-oriented design, while improving power efficiency, compromises the long term flexibility of such next-generation servers. Thus, the servers used in next-generation data centers must be capable of providing a cost effective solution that addresses current and future computational demands, provide a flexible platform capable of meeting evolving operational needs, while delivering improved power efficiency over legacy servers.

The challenges presented by the growing ubiquity of Internet-of-Things (IoT) devices are surprisingly similar to those presented by next-generation data centers. With literally billions of connected devices, cloud-based infrastructure must quickly evaluate high-bandwidth data streams and determine which data may be processed and which data may be safely dropped.

Next-generation platforms share several distinct requirements: increased bandwidth; increased flexibility to promote increased functionality; improved power efficiency (or reduced power consumption) and reduced footprint requirements. Heretofore, designers may address such varied demands by packing additional components on a standard printed circuit board. The limitations inherent in such single board solutions may not satisfactorily address the multiple demands placed on next-generation devices. Such limitations include: chip-to-chip bandwidth limitations based on interconnect density; the power demand of long distance traces between chips; and the increased physical size of printed circuit boards to accommodate the chips. Monolithic integration of system components provides a potential solution, however such integration does not readily permit the integration of system components, each of which may evolve at different rates. For example, a logic chip built using a newer technology may not easily integrate or lend itself to monolithic fabrication with a memory chip built using an older technology.

Conventional solutions are therefore unable to meet future demands of higher bandwidth, greater power efficiency, increased functionality, and increased operational flexibility—all in a physically smaller package and die architecture.

DETAILED DESCRIPTION

The systems and methods described herein include an electrical mesh network that couples a plurality of semiconductor intellectual property cores (hereinafter, “IP core” or collectively, “IP cores”) to a single base die that includes circuitry to support the collective operation of the IP cores (“support circuitry”). For example, the base die may include data storage circuitry, voltage regulation circuitry, and/or input/output (I/O) circuitry conductively coupled, via the electrical mesh network, to a plurality of IP cores disposed across the upper surface of the base die. Such an arrangement beneficially and advantageously permits the selection of IP cores or a mixture of IP cores that address a particular need or functionality while still retaining a “standard” or “generic” base die configuration. Example IP cores may include, but are not limited to, semiconductor dies having: processor core circuitry, graphics processing circuitry, field programmable gate array circuitry, neural network circuitry, quantum computing circuitry, and similar.

The use of an electrical mesh network to conductively couple the IP cores to the base die beneficially reduces the physical separation between components, thereby improving bandwidth while reducing transmission power losses. Further, such an architecture provides flexibility to accommodate relatively rapid evolution in IP core technology by simply attaching the newly developed IP cores to a base die that may evolve at a much slower rate. Thus, evolutionary changes in IP core technology are readily combined with the base die, without requiring a full semiconductor package redesign as would be needed if the IP core circuitry and the support circuitry found on the base die were formed monolithically. For example, patterning an orthogonal electrical mesh network on an upper surface of the base die may form a plurality of “nodes” where the individual conductors forming the electrical mesh network intersect—IP cores may be conductively coupled to each of some or all of the nodes included in the plurality of nodes. In addition, they failure rate for semiconductor dies increases with the number of components, circuits, and systems incorporated in the die (i.e., failure rate typically increases with the size and/or complexity of the semiconductor die). Reducing the component count on the IP cores beneficially reduces both: the physical size of the die and the failure rate.

Where traditional solutions positioned dies on a two-dimensional circuit board, the systems and methods described herein stack the dies in a three-dimensional space, reducing the footprint, improving communication speed, and reducing power consumption. More specifically, the systems and methods disclosed herein dispose each IP core circuit on a relatively small semiconductor die. The plurality of IP core dies may be physically, conductively and communicably coupled to a relatively large base die that provides the collective support circuitry used by the plurality of conductively coupled IP core circuits. Example support circuitry may include, but is not limited to, voltage regulation circuitry, input/output circuitry, data storage circuitry, etc.

An electronic device is provided. The electronic device may include: a printed circuit board; and a semiconductor package conductively coupled to the printed circuit board, the semiconductor package including: a base die having an upper surface and a lower surface, the base die including input/output circuitry; an electrical mesh network disposed proximate the upper surface of the base die and conductively coupled to the circuitry included in the base die, the electrical mesh network including: a first plurality of conductors wherein; each of the first plurality of conductors disposed proximate the upper surface of the base die and spaced apart from the remaining first plurality of conductors; and a second plurality of conductors, wherein: each of the second plurality of conductors disposed proximate the upper surface of the base die and spaced apart from the remaining second plurality of conductors; and each of the second plurality of conductors intersects and conductively couples to at least one of the first plurality of conductors; a plurality of IP cores, each of the plurality of IP cores including processor core circuitry, each of the IP cores conductively coupled to a node formed by an intersection of one of the first plurality of conductors with one of the second plurality of conductors.

A semiconductor package system is provided. The semiconductor package system may include: means for forming a first plurality of conductors proximate an upper surface of a base die; means for forming a second plurality of conductors proximate the upper surface of the base die, where: each of the first plurality of conductors disposed proximate the upper surface of the base die and spaced apart from the remaining first plurality of conductors; each of the second plurality of conductors disposed proximate the upper surface of the base die and spaced apart from the remaining second plurality of conductors; and each of the first plurality of conductors intersects and conductively couples to at least one of the second plurality of conductors to form an electrical mesh network, the electrical mesh network conductively coupled to at least the I/O circuitry included in the base die; means for conductively coupling each of a plurality of IP cores to a node formed by an intersection of one of the first plurality of conductors with one of the second plurality of conductors.

As used herein the terms “top,” “bottom,” “upper,” “lower,” “lowermost,” and “uppermost” when used in relationship to one or more elements are intended to convey a relative rather than absolute physical configuration. Thus, an element described as an “upper film layer” or a “top element” in a device may instead form the “lowermost element” or “bottom element” in the device when the device is inverted. Similarly, an element described as the “lowermost element” or “bottom element” in the device may instead form the “uppermost element” or “top element” in the device when the device is inverted.

As used herein, the term “logically associated” when used in reference to a number of objects, systems, or elements, is intended to convey the existence of a relationship between the objects, systems, or elements such that access to one object, system, or element exposes the remaining objects, systems, or elements having a “logical association” with or to the accessed object, system, or element. An example “logical association” exists between relational databases where access to an element in a first database may provide information and/or data from one or more elements in a number of additional databases, each having an identified relationship to the accessed element. In another example, if “A” is logically associated with “B,” accessing “A” will expose or otherwise draw information and/or data from “B,” and vice-versa.

FIG. 1 is a schematic of an illustrative semiconductor package 100 that includes an electrical mesh network 110 conductively coupled 160 to each of a plurality of semiconductor intellectual property cores 120A-120 n (singly, “IP core 120” collectively, “IP cores 120”) and conductively coupled 170 to a base die 130 that includes a plurality of support circuits 140A-140 n (collectively, “support circuitry 140”), in accordance with at least one embodiment described herein. The base die 130 may communicably couple 180 to a substrate 150, such as a multi-layer printed circuit board or similar. In embodiments, the electrical mesh network 110 includes a number of interconnected conductive pathways or members that couple each of the IP cores 120 to one or more neighboring IP cores 120, facilitating communication between the IP cores 120. In embodiments the interconnected conductive pathways or members forming the electrical mesh network 110 also conductively couple each of the IP cores 120 to the base die 130 facilitating communication between the IP cores 120 and the support circuitry 140. The base die 130 provides a “resource pool” shared by some or all of the IP cores 120. Beneficially, as new IP core technology is introduced, IP cores 120 may be substituted in the manufacturing process without requiring a redesign of the base die 130—reducing manufacturing costs and improving manufacturing flexibility and market responsiveness.

The electrical mesh network 110 includes a first plurality of conductors and a second plurality of conductors disposed at an angle to the first plurality of conductors such that at least one of the second plurality of conductors intersects at least one of the first plurality of conductors. In some embodiments, the electrical mesh network 110 may include a first plurality of conductors disposed parallel to each other across all or a portion of the upper surface 132 of the base die 130 and a second plurality of conductors disposed parallel to each other and orthogonal to each of the first plurality of conductors. Each intersection point where one of the second plurality of conductors contacts one of the first plurality of conductors defines one of a plurality of nodes on the electrical mesh network 110. In embodiments, each of the IP cores 120 may be conductively coupled to a respective electrical mesh network node. In embodiments, the electrical mesh network 110 may be deposited, patterned, formed, or otherwise disposed on, across, or about at least a portion of the upper surface 132 of the base die 130 using any currently available or future developed material deposition process or method. In some implementations, the electrical mesh network 110 may be formed on a single layer across all or a portion of the base die 130—i.e., the first plurality of conductors and the second plurality of conductors may be formed on the same layer (e.g., the same metal layer) of the base die 130. In some implementations, the electrical mesh network 110 may be formed in multiple layers across all or a portion of the base die 130—i.e., each of the first plurality of conductors and/or each of the second plurality of conductors may be formed on two or more different layers (e.g., adjacent or non-adjacent metal layers) of the base die 130.

Each of the semiconductor intellectual property cores (“IP cores”) 120 may include, but is not limited to, a reusable unit of logic, cell, or integrated circuit/chip/chiplet layout design. Example IP cores 120 include, but are not limited to, universal asynchronous receiver/transmitter (UARTs); central processing units (CPUs); graphics processing units (GPUs); IEEE 802.11 Ethernet controllers; Peripheral Component Interconnect (PCI) interfaces; storage devices; and similar. Each of the IP cores 120 includes circuitry (e.g., processor core circuitry) disposed on a relatively small (compared to the base die 130) integrated circuit. Each of the IP cores 120 has a lower surface 124 that is disposed proximate the electrical mesh network 110. In embodiments, the machine executable instruction sets that cause the operation of the support circuitry 140 in the base die 130 may be executed in whole or in part by processor circuitry and/or controller circuitry disposed in, on, or about the IP cores 120. In embodiments, each of the IP cores 120 may occupy the same area on the upper surface 132 of the base die 130. In embodiments, the IP cores 120 may occupy different areas on the upper surface 132 of the base die 130. In embodiments, the IP cores 120 may have a surface area of less than: about 25 square millimeters (mm²); about 20 mm²; about 15 mm²; about 12 mm²; about 10 mm²; about 8 mm²; or about 5 mm².

Each of the IP cores 120 includes one or more conductive fixtures 126A-126 n (contact bumps, pads, lands, grooves, pins, etc.—collectively “conductive fixtures 126”) disposed in, on, about, or across at least a portion of the lower surface 124 of the IP core 120. The one or more conductive fixtures 126 may be disposed in a fixed pattern or arrangement in, on, about or across the lower surface 124 of each of the IP cores 120 conductively coupled to the base die 130.

Maintaining the conductive features 126 in a fixed pattern or arrangement beneficially permits the replacement and/or substitution of IP cores 120 without requiring a redesign of the base die 130. For example, a newer IP core 120 _(NEW) may selectively replace an older IP core 120 _(OLD) in a particular semiconductor package design. Such replacement is greatly facilitated and redesign time and costs reduced or even eliminated when the arrangement of the conductive features 126 on the older IP core 120 _(OLD) match the arrangement of the conductive features found on the newer IP core 120 _(NEW). Since IP cores 120 may be readily substituted without requiring a complete rework of the base die 130, time-to-market is advantageously reduced and market responsiveness beneficially improved.

At least one of the one or more conductive fixtures 126 may conductively couple 160 the respective IP core 120 to the electrical mesh network 110. In embodiments, at least one of the one or more conductive fixtures 126 may conductively couple 160 the IP core 120 to support circuitry 140 disposed in the base die 130. In embodiments, an electrically conductive micro solder bumps, solder balls, solder paste, or similar material may physically and/or electrically conductively couple 160 the IP cores 120 to the electrical mesh network 110 and/or support circuitry in the base die 130.

The base die 130 includes support circuitry 140 that is deposited, patterned, formed, or otherwise disposed in, on, or about the base die 130. In embodiments, the support circuitry 140 may include, but is not limited to, one or more of the following: data storage circuitry; cache circuitry; input/output circuitry; processor voltage regulation circuitry (e.g., fully integrated voltage regulator or “FIVR” circuitry); communications interface circuitry; bus interface circuitry; and combinations thereof. The base die 130 may provide the substrate for the semiconductor package 100. In embodiments, the base die 130 is relatively larger than each of the IP cores 120. In embodiments, the base die may have an upper surface area of less than: about 3000 square millimeters (mm²); about 2500 mm²; about 2000 mm²; about 1500 mm²; about 1000 mm²; about 700 mm²; or about 500 mm². In embodiments, all or a portion of the peripheral regions of the base die 130 may include I/O circuitry. In embodiments, all or a portion of the central region of the base die 130 bounded by the peripheral regions may include cache memory circuitry. In such embodiments, the IP cores 120 may be coupled to the electrical mesh network 110 and/or base die 130 in the central region of the base die 130 that include the cache memory circuitry. Disposing the IP cores 120 proximate the cache memory circuitry in the base die beneficially reduces cache access time, thereby improving the performance of the semiconductor package 100.

At least a portion of the electrical mesh network 110 may be disposed, patterned, deposited, or otherwise formed in, on, about, or across at least a portion of the upper surface 132 of the base die 130. In embodiments, the electrical mesh network 110 may be formed as a single metal layer on the upper surface 132 of the base die 130. In other embodiments, the electrical mesh network 110 may be formed as a plurality of metal layers on the upper surface 132 of the base die 130. The electrical mesh network 110 may be formed using any currently available or future developed material deposition and/or patterning process or method. Non-limiting examples of material deposition and/or patterning processes include, but are not limited to, photolithography, printing, electroplating, electro-less plating, chemical vapor deposition, atomic layer deposition, physical layer deposition, and similar. The support circuitry 140 disposed in the base die 130 communicably couples 170 to the electrical mesh network 110 using conductors such as metal traces, vias, and similar that are disposed in, on, or about the base die 130.

In addition to conductively coupling to the electrical mesh network 110, at least some of the IP cores 120 may conductively couple to the support circuitry 140 disposed in the base die 130. In embodiments, one or more conductive structures 136 may be deposited, patterned, formed, or otherwise disposed in, on, about, or across all or a portion of the upper surface 132 of the base die 130 to couple at least one IP core 120 to the support circuitry 140 carried by the base die 130. Conductors, such as metal traces, vias, etc., couple the conductive structures 136 on the upper surface 132 of the base die 130 to the support circuitry 140.

A plurality of conductive features 138 may be deposited, patterned, formed, or otherwise disposed in, on, about, or across at least a portion of the lower surface 134 of the base die 130. The plurality of conductive features 138 conductively couple 180 the base die 130 (and the semiconductor package 100) to a substrate 150, such as a printed circuit board, motherboard, daughterboard, server blade, or similar. Conductors, such as metal traces, vias, etc., conductively couple the conductive features 138 on the lower surface 132 of the base die 130 to the support circuitry 140 and/or the electrical mesh network 110.

FIG. 2 is a partial cross-sectional elevation of an illustrative semiconductor package 200 that includes an electrical mesh network 110 communicably coupling a plurality of IP cores 120A-120C to a base die 130, in accordance with at least one embodiment described herein. As depicted in FIG. 2, semiconductor components, including active semiconductor components such as transistors, may be formed or otherwise disposed in a lower portion 210 of each of the respective IP cores 120. Disposing semiconductor components in the lower portion 210 of each of the IP cores 120 reduces the physical separation between the circuitry containing the respective semiconductor components and the electrical mesh network 110, beneficially improving performance while reducing power losses. Similarly, semiconductor components, including active semiconductor components such as transistors, may be formed or otherwise disposed in an upper portion 220 of the base die 130. In at least some embodiments, at least some of the semiconductor components disposed in the upper portion 220 of the base die 130 may form all or a portion of the support circuitry 140. In such embodiments, disposing semiconductor components in the upper portion 220 of the base die 130 reduces the physical separation between the support circuitry 140 and the electrical mesh network 110, further improving performance while reducing power losses.

One or more conductors 230, such as one or more vias or traces, may conductively couple at least a portion of the semiconductor components formed or disposed in the upper portion 220 of the base die 130 to one or more of the plurality of conductive features 138 (pads, lands, contacts, grooves, pins, etc.) deposited, formed, patterned, or otherwise disposed in, on, about, or across the lower surface of the base die 130. Conductive structures 240A-240 n, such as solder bumps, solder balls, clips, and/or pins, may be used to physically and conductively couple the base die 130 to the substrate 150.

One or more conductive structures 250A-250 n (collectively, “conductive structures 250”), such as one or more micro-bumps, solder bumps, solder balls, or similar conductively couple each of the IP cores 120 to the electrical mesh network 110 and/or the base die 130. In embodiments, the one or more conductive structures may include a plurality of micro-bumps arranged on a fine pitch array. For example, the conductive structures 250 may include micro-bumps formed from copper (Cu), copper containing alloys, silver (Ag), silver containing alloys, nickel (Ni), nickel containing alloys, and combinations thereof. In embodiments, the conductive structures 250 may include micro-bumps having a diameter of less than: about 50 micrometers (am); about 40 μm; about 30 μm; about 25 μm; about 15 μm; or about 10 μm. In embodiments, the conductive structures 250 may disposed on a pitch of less than: about 70 micrometers (am); about 60 μm; about 50 μm; about 40 μm; about 30 μm, or about 20 μm. In some implementations, a fine layer of solder similar electrically conductive material capable of reflow may be disposed proximate the conductive fixtures 126 disposed on the lower surface 124 of the IP cores 120.

FIG. 3A is a plan view of an illustrative semiconductor package 300 that includes an electrical mesh network 110 that includes a first plurality of conductors 310A-310 n (collectively “first conductors 310”) and a second plurality of conductors 320A-320 n (collectively, “second conductors 320”) disposed orthogonally to the first conductors 310, in accordance with at least one embodiment described herein. FIG. 3B is a cross-sectional elevation of the illustrative semiconductor package depicted in FIG. 3A along section line 3B-3B, in accordance with at least one embodiment described herein. As depicted in FIGS. 3A and 3B, the electrical mesh network 110 conductively and physically couples a plurality of IP cores 120A-120 n to a base die 130 that includes a plurality of support circuitry 140A-140 n.

Each of the IP cores 120 may include any number of circuits or circuitry. As depicted in FIG. 3A, each of the IP cores 120A-120 n include four processor core circuits 330A-330D (collectively, “processor core circuits 330”). Each of the processor core circuits 330 is conductively coupled to the electrical mesh network 110. The electrical mesh network 110 conductively couples each of the IP cores 120 to at least a portion of the remaining IP cores. The electrical mesh network 110 also conductively couples each of the IP cores 120 to the support circuitry 140 disposed in the base die 130.

The base die 130 includes a plurality of support circuits 140. In embodiments, the base die 130 may include a region containing cache storage circuits 330. In such embodiments, the IP cores 120 may be positioned proximate the region of the base die 130 that includes the cache storage circuits 330. Positioning the IP cores 120 proximate the cache storage circuits beneficially improves cache access times while reducing power consumption.

A number of support circuits 140, including input/output (I/O) circuits may be deposited, formed, patterned, or otherwise disposed in, on, across, or about the periphery of the base die 130. The I/O circuits may include any currently available or future developed I/O circuits 140. Example I/O circuits may include, but are not limited to, serial I/O interfaces, parallel I/O interfaces; wired I/O interfaces; wireless I/O interfaces; or combinations thereof. In the example semiconductor package 300 depicted in FIGS. 3A and 3B, the I/O circuits include general purpose I/O (GPIO) circuitry 140C; ultra-path interconnect (UPI) circuitry 140D, 140R; peripheral component interconnect (PCI) circuitry 140E, 140F, 140L, 140M, 140N, 140O; and RLink circuitry 140G, 140H, 140P, 140Q.

An additional number of support circuits 140, including data storage circuits may be deposited, formed, patterned, or otherwise disposed in, on, across, or about the periphery of the base die 130. The data storage circuits may include any currently available or future developed data storage technology. Such data storage circuits may include, but are not limited to, electrostatic data storage circuits; quantum data storage circuits; molecular data storage circuits; electroresistive data storage circuits; optical data storage circuits; or combinations thereof. In the example semiconductor package 300 depicted in FIGS. 3A and 3B, the base die 130 includes dual data rate (DDR) I/O circuitry 140A, 140B, 140J, and 140K.

The first plurality of conductors 310 includes conductors 310A-310 n deposited, formed, patterned, or otherwise disposed in, on, about, or across the upper surface 132 of the base die 130. In embodiments, the conductors 310A-310 n included in the first plurality of conductors 310 may be disposed on the same or different metal layers disposed in, on, or about the base die 130.

FIGS. 5, 6, and 7 are plan views of various illustrative, non-limiting, electrical mesh network 110 configurations. One of the benefits of the electrical mesh network 110 described herein is the capability to tailor the configuration of the electrical mesh network 110 to suit particular geometry, manufacturing, and/or operational needs.

The physical size, shape, and/or cross-sectional geometry of some or all of the conductors 310A-310 n, 320A-320 n included in the plurality of conductors 310, 320 may be the same or differ.

Each of the IP cores 120A-120 n may be conductively coupled, via one or more conductive structures 250, to a respective one of the plurality of nodes 510A-510 n on the electrical mesh network 110.

FIG. 6 is a plan view of an illustrative semiconductor package 600 that includes an electrical mesh network 110 in a “toroidal” network configuration in which each of conductors 310A-310 n included in the first plurality of conductors 310 and each of the conductors 320A-320 n included in the second plurality of conductors 320 “loop” between a portion of the IP cores 120 disposed on the upper surface 132 of the base die 130, in accordance with at least one embodiment described herein. In the toroidal network configuration depicted in FIG. 6, each IP core 120 is conductively coupled to four neighboring IP cores 120. As depicted in FIG. 6, using a toroidal electrical mesh network 110, the IP cores 120 may be arranged in a generally orthogonal pattern on the upper surface 132 of the base die 130. Each of the IP cores 120A-120 n may be conductively coupled, via one or more conductive structures 250, to a respective one of the plurality of nodes 610A-610 n on the electrical mesh network 110.

FIG. 7 is a plan view of an illustrative semiconductor package 700 that includes an electrical mesh network 110 in a “star” network configuration in which each of conductors 310A-310 n included in the first plurality of conductors 310 conductively couple each of the peripheral IP cores 120A-120H to a central IP core 120I, in accordance with at least one embodiment described herein. The distal (with respect to the central IP core 120I) termination point of each of the conductors 310A-310 n defines a respective node 710A-710 n on the electrical mesh network 110. In the star network configuration depicted in FIG. 7, each IP core 120 is conductively coupled to the central IP core 120I. As depicted in FIG. 7, using a star electrical mesh network 110, the IP cores 120 may be arranged in a generally circular or elliptical pattern about the periphery of the upper surface 132 of the base die 130.

FIG. 8 is a plan view of a base die 130 and an arrangement of IP cores 120A-120I to conductively couple to respective ones of each of a plurality of nodes 810A-810J included in the electrical mesh network 110 disposed on the upper surface 132 of the base die 130, in accordance with at least one embodiment described herein. In the example embodiment depicted in FIG. 8, the base die includes support circuitry 140A-140N. Support circuitry 140A-140D includes input/output circuitry. Support circuitry 140E-140L includes low-level cache (“LLC”) circuitry. Support circuitry 140M includes peripheral component interconnect express (“PCIe”) circuitry.

The area of the base die 130 occupied by the IP cores 120 is dedicated principally to last level cache memory circuitry, thus, the separation of the IP cores 120 from the support circuitry 140 carried by the base die 130 and the configuration of the electrical mesh network 110 beneficially does not increase the area occupied by the base die 130.

FIG. 9 is a high-level logic flow diagram depicting an illustrative method 900 for conductively coupling a plurality of IP cores 120 to a base die 130 using an electrical mesh network 110 disposed proximate an upper surface 132 of the base die 130, in accordance with at least one embodiment described herein. The method 900 may be used in conjunction with any of the methods 1000, 1100, and 1200 described in detail with regard to FIGS. 10, 11, and 12, respectively. Coupling the IP cores 120 to the base die 130 using an electrical mesh network 110 beneficially minimizes the physical separation between the IP cores 120 and support circuitry 140. Minimizing the distance between the IP cores 120 and the support circuitry 140 beneficially improves performance while reducing power consumption. Reducing component count on the IP cores 120 beneficially improves productivity by reducing the likelihood of component failure. The ability to couple evolving IP core technology to a base die 130 having an interface defined by the electrical mesh network 110 improves time-to-market, responsiveness, and productivity since time is not lost redesigning the base die for each improvement in IP core technology. The method 900 commences at 902.

In such embodiments, vias, traces, or similar electrically conductive elements may conductively couple one or more conductors 320A-320 n to one or more conductors 310A-310 n.

In embodiments. at least one of the conductors 320A-320 n included in the second plurality of conductors 320 intersects or is conductively coupled to at least one of the conductors 310A-310 n included in the first plurality of conductors 310.

In embodiments, one or more vias may additionally conductively couple some or all of the support circuitry 140 disposed in, on, or about the base die 130 to the conductive structures 138 disposed on the lower surface 134 of the base die 130.
